Is there any way of watching changes across packages in the G6 monorepo?

[ensconced]

Currently I can run npm run watch in the individual packages in the monorepo, but a change in one project isn't reflected in the other packages that depend on that project. For example, if I run npm run watch for packages/element, and also run npm run watch for packages/pc, when I make changes to the source code in packages/element, this does not trigger packages/pc to rebuild. Is there any way of achieving this currently?

It seems like father only watches the directory of the configured entry file, which is why this doesn't work. I notice each package also has a webpack.dev.config.js although these don't seem to be referenced from anywhere. Using webpack would make this a bit easier because by default it watches all the files from the import graph starting from the entrypoint.

Something like this does work:

# initial repo setup
yarn install
yarn bootstrap
yarn build:all

# watch and rebuild all individual packages
yarn lerna run --parallel watch

# then in another shell...
cd packages/G6
yarn run webpack --config webpack.dev.config.js --mode development

Then father will rebuild any of the packages when their source TS files change, and webpack will detect the newly built files from the packages that it depends on and trigger its own rebuild. It works but it's a bit cumbersome and I don't think the father build outputs sourcemaps which isn't ideal.
